8 gur of corn/year for a field laborer. 100 shekels/year for
a day laborer. This suggests that 1 gur= aprox 12 shekels.

Buildinga house--2 shekels per 35 sq meters of
"surface."

Building a twenty ton boat; 2 shekels = one or two weeks pay--something wrong.

Hiring it is 1/6 shekel/day !!!
(includes crew?)

Hire of ferry boat is 3 gerahs/day = 3/20 shekels

Hire of freight boat is 2.5 gerahs/day =2.5/20 shekels

Hiring figures are consistent,
building figure is not.

Sailor's pay 6 gur of corn/year = 72 shekels

Plow oxen rental 4 gur of corn/year = 48 shekels

Her cattle 3 gur/year = 36 shekels

Field laborer gets 8 gur = 96 shekels

Ox driver gets 6 gur =72 shekels

Herdsman gets 8 gur = 96 shekels

Day laborer gets 100 shekels/year (assuming he works 365
days/year)

Artisans get a little less. (???)

Note: The consistency here is
artificial, since I figured out the value of a gur in shekels by assuming that
the two groups of wages were consistent.

The value of a ka of corn?

Hire of an ox for threshing is 20 ka of corn

an ass for threshing, twenty ka of corn

(Hire of a young animal for threshing is 10 ka of corn

hire of oxen, cart and driver is 180 ka of corn per day

cart alone is 40 ka per day

If we assume the cart has two oxen, and the cost per is the same
as for threshing, then the driver is costing 100 ka of corn/day. That seems a
bit high, given that the rental of oxen seems to be about half a laborer's
wage--perhaps four oxen to the cart? Figure that a driver gets between 40 and
100 ka/day, which is about 80 shekels/year. If we again assume working every
day, that gives us:

182-456 ka of corn = 1 shekel.Scale up the value of the ka according to how many days less
than 365 someone works.
